But the main thing here is an unusual date display. In the normal inactive state, the hand freezes at "12" without overlapping the off-centre dial. The button on the left side of the case allows the hand to be activated: the hand instantly moves to the correct date, and then moves forward one step per day at midnight. With another press of the button, the hand returns to its original position, and mechanical memory allows it to return to the correct date when required.
The date can be set using the corrector pusher at 8 o'clock or manually using the crown, adjusting the time as usual. The red tip of the date hand is shaped like the letter A (Armin).
The movement is housed in a 43,4 mm case.
Complementing the 12,6 mm case is a steel bracelet that combines polished and satin-brushed links.
